I wrote one with twisted.. it's quite easy and minimal..
you can start hooking stuff to it, I only use "dataReceived"
as I only need to watch what cmds are imap client sending.
from twisted.protocols.portforward import ProxyFactory
from twisted.protocols.portforward import ProxyClientFactory
from twisted.protocols.portforward import ProxyClient
from twisted.protocols.portforward import ProxyServer
from twisted.internet import reactor
class PS(ProxyServer):
def dataReceived(self, data):
print "PS->dataReceived(%s)" %repr(data)
ProxyServer.dataReceived(self, data)
pfactory = ProxyFactory('192.168.1.1',143)
pfactory.protocol = PS
reactor.listenTCP(143, pfactory)
reactor.run()
this will bind to port 143 and proxy all requests to the real imap
server at 192.168.1.1, while printing the commands being sent to stdout.
Here, my proxy runs on different box than imap server... if you need to
put both of them on same box you'll need to change the port number of ,
either imap server, or imap proxy.
well..
hope it helps
